If I have historical data for USD/CAD and USD/JPY, isn't it just some simple math to generate CAD/JPY? Am i overlooking anything important here?

Since USD and CAD are nearly 1-to-1, your math might possibly have a mistake that wouldn't be obvious in this case. Therefore I suggest you test out your math on some example problems in which no two currencies are anywhere near 1-to-1. Perhaps, JPY-ZAR-USD ?? See below:

Its pretty close, about 0.1% difference.

How many pips is 0.1%? (I'm not a forex trader and don't have this kind of information at my fingertips....)

Here's some data of each cross currency, the actual JPYCAD and a calculated JPYCAD. Looks close, but not exact. Room for arbitrage I suppose.

Assuming a pip on the ZAR/JPY is 0.0001, then its 130 pips.

I'm trying to revisit this method. Doing the math works ok at fixed points in time like the open and close. The highs and lows are trickier because they wouldn't occur at the same point. I wonder if there is a "good enough" method?
